Jersey City public schools are expected to reopen for a half-day Wednesday, nine days after Hurricane Sandy battered the region and left the city largely powerless.

Schools Superintendent Marcia V. Lyles announced the decision in a letter posted this afternoon on the district’s website, saying some schools still do not have power but the district is pushing ahead regardless.

“Hurricane Sandy has left its mark on every one of us,” Lyles writes. “We did not anticipate that the city would be nearly crippled and we would have to close schools for a week.”

The district’s schools are clean, safe and flood free, Lyles adds, and the food supplies should be replenished by Wednesday.

The district will hold classes Thursday and Friday, days that had previously been scheduled vacation days because of the annual teachers conference in Atlantic City. With the conference canceled, classes will be on.

Schools with power will have class from 8 a.m. to 1 p.m. on Wednesday, including breakfast and lunch, according to Lyles’ letter. Students in schools that still don’t have power will be bused elsewhere, where classes will run from 8:45 a.m. to 2 p.m.

As of this afternoon, schools without power are Schools 14, 15, 16, 22, 23, 23 annex, 24, 30 and 33 and the Martin Center for the Arts.

The Morning Stars and CASPER programs are canceled for the rest of the week.
